Never share the six-digit registration code.

Messages from “friends” asking for urgent money.
Fake job offers and task scams.
Links to fake prize or KYC pages.
Unknown international calls.

If Your Account Is Taken Over

Re-register the app with your phone number to log out the attacker.
Enable two-step verification.
Inform contacts to ignore suspicious messages.
Report to the app’s support and to cybercrime.gov.in if needed.

Group Safety Settings

Setting	Why
Who can add you to groups	Prevents spam and scam groups
Disappearing messages	Limits stored sensitive chats
Media auto-download	Prevents unwanted files
Admin-only messaging (for admins)	Controls large group spam

Handling Suspicious Messages

Do not click links from unknown contacts.
Verify “friend in need” requests by calling.
Report and block spam accounts.
Do not forward unverified information.

Business Messaging Safety

Verify official business accounts before sharing details.
Businesses never need your OTP to process orders.
Beware of fake customer care numbers.
Use official apps and websites for payments.

Chat Backups

Chat backups stored in the cloud may not always be end-to-end encrypted by default. Enable encrypted backups where available and protect the backup password. This keeps your chat history private even if cloud accounts are compromised.

Using Messaging Apps on Computers

Linked computers can access your chats. Log out of web or desktop sessions on shared computers and review linked devices regularly.

Small settings changes significantly reduce the risk of scams and account takeovers.

A Real-Life Scenario

Seema received a WhatsApp message from an unknown number claiming to be her relative asking for urgent money. She called her relative directly and discovered it was a scam. She then enabled two-step verification, adjusted privacy settings so only contacts could see her profile photo and turned off automatic group additions. She also warned her family about similar scams.

Your Messaging Security Checklist

Enable two-step verification with a PIN.
Adjust privacy settings for profile photo, last seen and groups.
Verify urgent money requests through a phone call.
Never share verification codes with anyone.
Report and block suspicious accounts.

Messaging apps are convenient but also targeted by scammers. Stay alert and secure your account.

Common Messaging Security Mistakes

Sharing verification codes: Scammers often pose as friends to request codes. Never share them.
Joining unknown groups: Groups can spread scams and malicious links.
Clicking shortened links: Check the real destination before tapping.
Downloading unknown files: Files from strangers can contain malware.
Keeping profile public: Limit profile photo and status visibility to contacts.
Using unofficial app versions: Modified apps can steal data and get accounts banned.
Ignoring backups encryption: Enable encrypted backups where available.

Simple habits keep your chats and personal data safe. Share these tips with your family too.

Practical Tips From Experience

Teach elderly family members about common messaging scams, such as fake relatives asking for money, fake job offers and lottery messages. Encourage them to call you before acting on any urgent request. Regularly review which groups you belong to and exit ones you no longer need.

Enable disappearing messages for sensitive conversations if your app supports it. Be careful when using messaging apps on shared or public computers, and always log out afterwards. If your phone is lost or stolen, use the app official process to deactivate your account on that device and inform contacts. Keep your app updated to benefit from the latest security improvements.

Enable two-step verification and never share verification codes.
Limit profile visibility and turn off automatic group additions.
Verify urgent money requests with a phone call before acting.
Use only official app versions and report suspicious accounts.

Bottom line: verify first and never share codes.
